This document presents design techniques and reference circuits that power Virtex™-4 FXRocketIO™ multi-gigabit transceivers (MGTs) operating at data rates below 3.125 Gb/s.When using multiple transceivers, it is sometimes preferred to power them from a switchingpower supply. However, switching power supplies generate noise that affects transceiver

For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-stage charging schemes. The majority of batterycharger ICs available today lock the user into one fixedcharging regimen, with at best a limited number ofcustomization options to suit a variety of application needsor battery types. The LTC®1325 addresses these shortcomingsby providing the user with all the functionalblocks needed to implement a simple but highly flexiblebattery charger (see Figure 1) which not only addressesthe issue of charging batteries but also those of batteryconditioning and capacity monitoring.

摘要 本研究计划之目的，在整合应用以ARM为基础的嵌入式多媒体实时操作系统于H.264/MPEG-4多媒体上。由于H.264是一种因应实时系统(RTOS)所设计的可扩展性串流传输(scalability stream media communication)的编码技术。H.264主要架构于细细粒可扩展(Fine Granula Scalability,FGS)的压缩编码机制。细粒度可扩展压缩编码技术是最新MPEG-4串流式传输标准，能依频寛的差异来调整传输的方式。细粒度扩展缩编码技术以编入可选择性的增强层(enhanced layers)于码中，来提高影像传输的质量。本计划主要在于设计一种简单有效的实时阶层可扩展的影像传输系统。在增强层编码及H.264的基本层(base layer)编码上使用渐进的细粒度可扩展编码(Progressive Fine Granularity Scalable,PFGS)能直接使用H.264的格式特色来实现FGS。同时加入了LB-LLF(Layer-Based Least-Laxity-Fir stscheduling algorithm)的排程算法，来增 进网路传输影像的质量。由实验结果显示本系统在串流影像质量PSNR值上确有较佳的效能。
